N2 - Workshops are an established technique for requirements elicitation. A lot of information is revealed during a workshop, which is generally captured via textual minutes. The scribe suffers from a cognitive overload due to the difficulty of gathering all information, listening and writing at the same time. Video recording is used as additional option to capture more information, including non-verbal gestures. Since a workshop can take several hours, the recorded video will be long and may be disconnected from the scribe's notes. Therefore, the weak and unclear structure of the video complicates the access to the recorded information, for example in subsequent requirements engineering activities. We propose the combination of textual minutes and video with a software tool. Our objective is connecting textual notes with the corresponding part of the video. By highlighting relevant sections of a video and attaching notes that summarize those sections, a more useful structure can be achieved. This structure allows an easy and fast access to the relevant information and their corresponding video context. Thus, a scribe's overload can be mitigated and further use of a video can be simplified. Tool-supported analysis of such an enriched video can facilitate the access to all communicated information of a workshop. This allows an easier elicitation of high-quality requirements. We performed a preliminary evaluation of our approach in an experimental set-up with 12 participants. They were able to elicit higher-quality requirements with our software tool.
